MACHINE FOR PUNCHING,

CUTTING, SHEARING, 80C.

SPECIFICATION forming part of Letters Patent No. 621,097, dated March14, 1899.

Application filed May 16, 1898.

, clear, and exact description.

The present invention relates to apress in which the pressing-stamp hasnot merely a single tool or die, matrix, or the like, but by specialconstruction of the head of the press any desirable number of toolsentirely different in dimensions or in their operations may beintroduced.

The invention is shown in the annexed drawings, in which Figure l is afront view of a press constructed according to this invention; Fig. 2, apart sectional side elevation, andFig. 3 a plan of the same. In thesuitably-constructed machine-frame athe eccentric-shaft o, furnishedwith the eccentric b and the handle d, is seated. In place of the handlecl a pulley of suitable dimensions may be employed equally well, or thewhole driving apparatus may be entirely replaced by one of thosehitherto in use and suitable for the purpose.

The press-head e of the machine is not massive in construction, ashitherto, but in its outward appearance more resembles a frame. It isfurnished at the back, as ordinarily, with dovetails, which, exactly asin other apparatus of the kind, can be forced by means of screws andadjusting-blocks to slide properly and surely on the prismatic guide f.In the middle of the press-head e is an opening g, bounded by arcs ofdifferentradii and acting as a cam. In the lower slide of the opening gis a small semicircular groove h, which serves for guiding thepressure=block 't'. The

eccentric b, in the present instance the pressdriving pin, runs betweenthe upper-limit curve of the opening 9 and the block 13, and thereforeraises the whole apparatus, while when the eccentric-pin descends thewhole press-head is pressed down with the assistance of thepressure-piece i.

The revolving ring is a characteristic feature of this press. It isexactly fitted onto Serial No. 680,862- (NdmodeL) other in regulardegrees, or an gle-iron cutters,

shears, punches, or other implements may be placed on the revolving ringin any desired order. The fixing of the ring to the piece Z for thepurpose of exact adjustment of the tools is efiected in a suitablemanner by means of a set-stud, a block, or in any other suitable way.The motion of the eccentric-shaft c or of the eccentric b is followed bythat of the Whole revolving ring, as well as that of the instrumentwhich. has been adjusted for cutting, the motion of the ring and head 6being regularly up and down.

At a suitable distance below the revolving ring or the press-head asimilar support to the one Z, hereinbefore referred to for receiving therevolving ring, is fixed onto the machineframe Cb. This supportalsocarries a revolving ring, which can be fixed by means of blocks or anyother suitable means, such ring conveying in the same graduation thematrices or counterimplements corresponding to the punches or the like.

As will be seen from Fig. 1, the rings in the machine represented carryan angle-iron cutter, shears, and six perforating or hole punches. Thetools can, as a matter of course, be put together in any desired manner,however difierent the driving apparatus for the machine may be andwhatever may be the fitting out of the several parts without in any Wayaffecting the scope of the invention.

What I claim, and desire to secure by Letters Patent, is'- 1. Inamachine for punching, cutting 82c. the combination with asupporting-frame, of a vertically-movable head, a tool-holder car riedby and adapted to be adjusted circumferentially upon said head,and aholder adapted for annular adjustment and also adapted andcireumferentially adjustable upon said head, and having a slot throughwhich the eccentric-pin projects and bears upon the upper Wall of theslot, the opposite Wall of the latter being provided with a groove, anda piece having one end hearing in said groove and shaped at the oppositeend to form a hearing for the eccentric-pin.

In Witness whereof I subscribe my signature in presence of twoWitnesses.
